sub

The sub element indicates that text should appear with subscript
highlighting, or placed lower in relationship to the surrounding text. Subscripted text is
often a smaller font than the surrounding text. Formatting might vary depending on your output process. This element is part of the highlighting domain. Use this element only when a more semantically appropriate element is not available.

Note: Style sheets can be used to format the
sub element differently, just like any other element
can be restyled. Thus, it is not the case that content in
sub elements will necessarily be rendered as
subscript.
